"Finally, the pool should be emptied and refilled with clean water, then emptied again and refilled after one week. Fluoridated water should then be conditioned prior to stocking with fish. Once the pool has been stocked and plant life established, it should not be disturbed for at least a year, except for occasional topping-up with fresh water. Initially, the water may become cloudy, but this cloudiness should disappear again as the plant and fish life in the pond settle down." soundsa like a balls ache.
